The AMO M10 is a new low cost industrial pressure transmitter designed for general purpose pressure measurement.

This sensor is rugged and durable, providing accurate measurement even under harsh conditions, available in gauge, absolute and sealed gauge versions. The MPM489 model is the ATEX approved version certified to ATEX Exia IIC T4 Ga. (Read More)


The Diaphragm is the sensing element in these pressure sensors comprised of multiple layers including a silicone substrate which has excellent piezoresistive properties. When pressure is applied, the diaphragm flexes and causes a deformation in its crystal lattice which modifies the band structure placed on the diaphragm and changes the resistivity of the material. Semiconductor resistors on the front side transduce this tension into resistance changes by means of the piezoresistive effect.
Silicone has Young’s Modulus of about 2*105 MPa, which is same as that of steel, but silicone is as light as aluminium, with a mass density of about 2.3 g/cm3 . Its melting point of about 1400°C makes silicon dimensionally stable even at elevated temperatures. It has a thermal expansion coefficient 8 times smaller than that of steel, and more than 10 times smaller than aluminium. It is an elastic material with no plastic or creep below 800°C. The major advantage of this fabrication technique guarantees high precision and large volume production at low costs.

Both models are constructed from stainless steel with a choice of grades to ensure application suitability. Process connections and operating pressure ranges can be specified as can options for signal output type, diaphragm material and electrical connections.  Every device is temperature compensated and calibrated and supplied with a traceable serial number and calibration certificate. The electronics incorporate a microprocessor based amplifier which means that there are no adjusting pots and therefore the electronics are very stable, especially in high vibration and high shock applications.
